This one-piece toilet is super quiet with a siphon flushing system thanks to the glazed system, which doesn't produce a noisy sound when you flush. At the same time, it packs a powerful performance since it's designed to prevent clogs, leaks, and plumbing issues.

Plus, this toilet reaches your standard chair height to ensure it's accessible to your household. As such, sitting down and standing up is much more convenient for adults.

The second quietest flushing toilet is the TOTO Drake, a two-piece ADA compliant toilet with an elongated bowl. This powerful unit can flush at a powerful rate of 1.6 gallons per flush and has a durable build that makes it ideal for commercial and residential settings. So, whether you want quiet flush toilets for your home or business, this TOTO toilet is a great option.

The flush valve that comes with the GMAX flushing system is much larger than that found in standard toilets, making it ideal for dispelling liquid and solid waste. Thanks to the siphon jet, this toilet draws water much faster and pushes it out with more force to ensure a smooth performance.

This quiet toilet also features a concealed design which makes it look smooth and sleek while easing the cleaning process. Plus, there are enough color variations to find the right match for your bathroom interior. So, if white isn't the color you prefer, you can choose another for complete satisfaction.

The next unit on our list of the best quiet flush toilets is the TOTO Ultramax II, a high-quality toilet made from durable vitreous china material. This gravity flush toilet comes with TOTO's Tornado flush system, which delivers a powerful performance to carry solid and liquid waste away without a struggle.

The elongated toilet bowl features a CEFIONTECT glaze which prevents the adhesion of particles to the toilet. This lubricious quality makes this toilet easy to clean and maintain, which is why it's among the best quiet toilets you can buy. The universal height of this model is the most ideal for a wide range of users, including disabled individuals, since it's ADA compliant.

The dual flush system cleans the rim and toilet bowl with each flush since it creates a robust centrifugal motion that carries away lingering waste. Plus, if you are looking for a toilet with high water efficiency, this is the optimal choice since it delivers 1.28 gallons per flush.


  • Quiet performance
  • Low water consumption
  • Ideal height
  • Fast flushing


  • Toilet seat available at additional expense

4. Niagara Stealth 0.8 GPF Toilet

Niagara 77001WHCO1 Stealth 0.8 GPF Toilet with...
  • ADA Compliant: 0
  • Bowl Shape: Elongated
  • Flush Type: Gravity
  • Gallons Per Flush: 0.8
  • Hygienic Surface Treatment: 0

Another quiet toilet you can choose for your home is the Niagara Stealth Toilet, an ADA-compliant toilet featuring a higher toilet seat. As such, it's a great choice for people who need support getting up and sitting on the toilet. At the same time, you won't have a hard time rising and sitting on this toilet since it's 15 inches higher than standard toilets.

Those looking for extra comfort and support will be glad to know that this unit comes with an elongated toilet bowl. Unfortunately, this means that it also occupies extra bathroom space compared to typical toilets, but the convenience it provides is definitely worth it.

Something else that makes this quiet flush toilet an ideal selection is the low water consumption rate of 0.8 gallons in a single flush. If you wanted a toilet with water-saving features, this is it. It might seem like 0.8 gallons is a small amount of water, but the gravity flushing system delivers enough power to wash away the waste in the bowl without difficulty.

The primary disadvantage of this unit is that the higher seat is harder to reach for children since it's a bit high.


  • Ample support from the higher seat
  • Low water consumption
  • Robust flushing system


  • Not great for small kids
  • Not ideal for small bathrooms

It also contains siphon jet bowl technology with works with the PowerWash rim for a great flushing performance. So you won't have to worry about solid waste clogging this toilet any time soon. Unfortunately, the toilet seats for this model are sold separately, which means that you'll have to pay extra to get them.

This dual flush toilet allows you to choose between 0.92 and 1.28 gallons per flush for full control of your water consumption. Plus, since the trapway is fully glazed, you don't have to worry about particles sticking onto the bowl.


  • Easy installation
  • Comfortable height
  • Water-saving capabilities
  • Powerful flush


  • Additional costs for the seat

Factors to Consider When Choosing the Best Quiet Flush Toilets

1. Types of Toilets

The first consideration to make is whether you want a one-piece or two-piece toilet. Let's look at them in detail below.

  • One-Piece Toilet

A one-piece toilet combines the toilet tank and bowl into a single unit. They are expensive but are much easier to clean than their two-piece counterparts.

  • Two-Piece Toilets

A two-piece toilet has the tank separate from the bowl. As a result, it's necessary to join them during the installation process. However, they are the most available option and are popular among homeowners because of their affordable pricing.

2. Flushing Mechanism

One of the essential features you should look at when choosing the quietest flushing toilet is the flush function. There are various flushing systems available; let's discuss them below.

  • Gravity Flush Toilets

These toilets are the most common and are designed to use the downward power of gravity to direct the water from the toilet tank after pulling the handle. The momentum the water carries as it rushes down the bowl pushes the waste into the drain. They are very efficient, easy to repair, and affordable.

  • Pressure Assisted Toilets

In the past, these toilets were popular in commercial settings because they were quite costly. Fortunately, as pressure assistance technology gets cheaper, they get into residential spaces. The pressure assisted toilets come with a compression tank that delivers the additional pressure necessary to pull the water and matter into the drain. They offer a powerful flush while using less water and have a compact design that makes them ideal for small bathrooms.

  • Tankless Toilets

Rather than a tank for supplying the flushing water, tankless toilets use a direct water line that attaches to the bowl. However, they need high water pressure or mechanisms that can power the flush, making installation complex, especially if you don't have adequate water pressure.

Fortunately, they don't require a tank which makes them a space-saving option. They can also provide a simple interior aesthetic when compared to tanked toilets.

  • Dual-Flush Toilets

If you are looking for the ultimate efficiency, dual-flush toilets are the best option. They allow you to flush waste based on the amount of water you think is necessary. This means that they offer different water consumption rates, enabling you to save on water deliberately. Plus, these toilets have a reduced chance of clogging.

3. Toilet Bowl Shape

Most quiet flush toilets will come with a round bowl or elongated bowl. The round toilet bowl takes a smaller size and is a great option for bathrooms with limited space. Models with round toilet bowls are also more affordable than elongated toilets, making them popular among buyers with a strict budget.

Elongated bowls take a more oval than round shape and are longer than round toilet bowls by a few inches. Most people find them comfortable, which is why they are popular despite their higher price tag.

4. Water Consumption

The amount of water a toilet uses is always among the first considerations that users have. If you want to determine the level of water you'll be using, you should check the GPF (Gallons Per Flush). This unit is also referred to as the flow rate and can help you save on water consumption if you prioritize efficiency.

Standard toilets have a rate of about 1.6 GPF, but models can be designed to deliver a powerful flush with less water. The most efficient models are tankless, pressure-assisted, and dual flush toilets. Such toilets can help you cut water bills by a good percentage which can work well for your finances.

5. Configuration

Your quiet toilet can be installed in three different ways;

  • Floor Mount Toilets

Most toilets are installed directly into the floor, hence the term floor-mounted. They are the ones commonly seen in homes and various establishments.

  • Wall-Mount Toilets

These are less common and attach to the walls rather than the floor. As a result, they hang above the ground providing an aesthetic aspect. Unfortunately, they are quite pricey and have a complex installation process.

  • Freestanding Toilets

These sit on the floor but don't have to be attached, making them easy to install and clean.

6. Height

Most toilets reach about 15 inches high, but this tends to be a bit low for adults and can make it harder to sit and stand. So, most people prefer something close to 19 inches or more for ideal comfort. However, these tend to be unsuitable for small kids.

7. Comfort

If you are considering comfort as you look through the best quiet flush toilets, there are specific features you'll need to be keen about. First, a toilet with an elongated bowl will be more comfortable than a round one since it's longer. So, if you are planning for a high-budget toilet, you can go with an elongated toilet.

Another issue is the toilet seat, especially since the seat is the part you make contact with. This is where comfort should be prioritized, even though it is an accessory that you can add along the way.
